How to install Deck Skirting

Here is a nice example of how you can install skirting, fascia and an access door under your deck.

Install a nailer board between support posts to attach the bottom side of the skirting or install 2x4 vertical framing flush on the outside of the frame.

Use a piece of scrap material to space your skirt boards. In this case we used a 1/2" thick piece of base trim. Next, fasten each skirt board to the top and bottom of the skirt frame. Keep the bottom of the skirt at least 1" above the ground.

Start each section using a level. Use the level every 4-5 boards to make sure the boards are still plumb.

Install vertical 2x4 framing to create the access door opening.

Fasten the vertical 2x4 framing to the deck frame using screws. This technique could also be used to support all the skirt framing if you don't have any available support posts to attach to.

Build an access door using a Z brace. Make sure the angle brace starts at the bottom hinge and ends at the latch. Cut a 45 degree bevel at the end of the trim under the hinges to allow the door to swing, as shown in the first slide.
